There are class tiers, but it seems like most can be put to use quite well even if they arent top tier. Top tier combat seems to boil down to feints, guard breaks and parries, lots of reads and mindgames and basically no spamming. A bit similar to M&B but much easier to grasp, and all the parts are much more necessary to win. Being defensive is beneficial which can be rather boring, but duels last shorter than the average crpg duel so to me its still in a fine spot.
Cant wait for Xena Valkyrie buffs, just a slight boost in damage would be sick. Having a good time still, you know its a good gameplay when you can get locked in hours upon hours of practise, and still enjoy it thoroughly. Same happens to me in Rocket League, nice to have other semi competitive games to swap between.
